Just a few:

and it looks like some company made a Batmobile Transformer:
Some really good stuff here. Metroplex in the back is pretty awesome. The dude to his left (our right) is built from the pieces of Metroplex. It is one toy. If there is a little black car in Metroplex's right (our left) boob...that would be awesome. I'd say the Metroplex is worth anywhere from 50 - 75 dollars. He looks to be in good shape.
Optimus Prime on the right is a second wave (I can tell by the light blue color legs he has. First wave Prime would have super deep/rich purple). With no parts whatsoever, still around 10 bucks. If it were first wave, it would be 20.
The cop car on the left is named Siren. He is a headmaster so his head will come off and Transform into a little dude. With what I see, probably around 50 dollars for him. The head alone is worth around 40 dollars as those heads easily get lost over the years and people need that head (pun intended) to complete the toy.
The Mircroscope is Perceptor. Total pimp. With what I see...probably 15 bucks. He looks to be in really good shape.
The hot rod dude is Rodimus Prime. He is missing just about everything, but still would get you 10 bucks.
The Stegosaurus is name Snarl. Without any parts, probably 15 to 20 dollars.
Last but not least is the saddest thing I have seen...parts of Megatron. He looks like he has seen better days. Still probably 10 to 15 dollars.
The market for old Transformers toys (just the bodies/without any parts) has skyrocketed in the last year. People have been spending huge dollars on old junk bodies to customize, repaint and re-purpose.
